Methods and systems for data collection in an environment including pumps and fans are disclosed. A monitoring system may include a data collector communicatively coupled to a plurality of input channels, wherein the input channels are communicatively coupled to sensors measuring operational parameters of a pump or fan. A data storage may store one or more frequencies related to an operation of the pump or fan, and a data acquisition circuit may interpret a plurality of detection values from the collected data. A frequency evaluation circuit may detect a signal on one of the input channels at a frequency higher than the one or more frequencies at which the pump or fan operates.

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives, from a first base station, a data transmission on a first cell using a first RAT. The UE determines a CRS transmission using a second RAT on a second cell from a second base station. The UE determines that the CRS transmission on the second cell interferes with receiving the data transmission on the first cell at the UE. The UE applies an interference cancellation on the first cell to mitigate an interference from the CRS transmission on the second cell to the data transmission on the first cell.

The present embodiments relate to a method and device for obtaining location information of a terminal by using a wireless communication system. Provided according to an embodiment is a device for acquiring the location information of a terminal, the device comprising at least one downlink signal receiver, at least one uplink signal receiver, and a controller for controlling the downlink signal receiver and uplink signal receiver, wherein the controller configures uplink resource assignment information on the basis of control information received by the downlink signal receiver and determines whether an uplink signal is received, on the basis of the uplink resource allocation information.

This application provides a data stream processing method and a network element device. The method includes: obtaining, by a first network element device, a first data stream, where the first data stream includes a first data unit and a first data padding unit; and adjusting, by the first network element device, a quantity of second data padding units in the first data stream, where a relative position of the first data unit and the first data padding unit in the first data stream is the same as a relative position of the first data unit and the first data padding unit in a second data stream, and the second data stream is an adjusted first data stream. When adjusting a rate, the first network element device does not add or delete the first data padding unit in the first data stream.

A method includes determining a delivery performance of a data flow being transmitted from a first network equipment to a second network equipment over a network; determining whether the network is congested based on the determined delivery performance of the data flow being transmitted to the second network equipment; and pacing delivery of the data flow to the second network equipment by reducing a rate at which the data flow is delivered to the second network equipment when the network is determined to be congested.

An encoding method and apparatus, an electronic device and a storage medium are provided. The method includes: determining a target quantity of segments of a sequence to be coded according to a length of the sequence to be coded and a transmission code rate; performing segmentation on the sequence to be coded according to the target quantity; coding each sub-sequence obtained after segmentation, and concatenating sub-sequences after coding.

The present disclosure relates to an apparatus and a method for supporting an improved communication speed in a wireless power transmission system. In such present specification, provided is the method comprising the steps of: transmitting at least one data packet to a wireless power reception apparatus; receiving, from the wireless power reception apparatus, a first request packet requesting a change in a communication speed of the wireless power transmission apparatus; and changing the communication speed of the wireless power transmission apparatus on the basis of the first request packet, and transmitting, at the changed communication speed, a first response packet in response to the first request packet to the wireless power reception apparatus.

Techniques that provide link establishment between a radio equipment controller (REC) and a radio equipment (RE) in a fronthaul network are described herein. In one embodiment, a method includes performing, Common Public Radio Interface (CPRI) Layer 1 (L1) link auto-negotiation operations to establish a CPRI link between the REC and RE. A proxy slave may achieve a hyper frame number (HFN) synchronization with the REC at a link bit rate for a first CPRI bit stream and communicate the first CPRI bit stream and the link bit rate to a proxy master. The proxy master may communicate a second CPRI bit stream to the proxy slave to transmit to the REC. The L1 link auto-negotiation operations are completed and CPRI link is established between the REC and the RE when the REC achieves a HFN synchronization for the second CPRI bit stream.
